partsize(1M)

partsize -- return the size of the active UNIX System partition

Synopsis

partsize [-ds] raw-device

Description

The function of partsize is to print the size of the active UNIX System partition for the raw-device disk drive. The size value returned is in megabytes (MB = 2E20 bytes). This command is intended for use with the installation scripts, but is available for general use. If the system cannot retrieve a valid partition table, there will be a non-zero exit value. If a valid partition table is found, but no active UNIX system partition is found, it will display a value of zero.

raw-device: the required raw-device argument is the character special device for the disk drive to be accessed. It should be the slice 0 device to represent the entire device (for example, /dev/rdsk/0s0 or /dev/rdsk/c0b0t0d0s0).

Options

partsize takes the following options:

-d: Displays the disk geometry and the configuration layout of the four optional disk partitions. Disk partitions are initialized using the fdisk(1M) command. Unused partition entries contain the value 100 in the OS field.
-s: Displays the size of the entire disk in megabytes. The value can be greater than the size of the UNIX System partition if multiple partitions were allocated.
